The correct and best answer would be letter B. To find the percent of a discount, you have to find or solve for the percent of increase from the new price to the original price. This is because you usually have the new price being given to you so you compare it with the old price to know the percent discount.

mylen [45]

Answer:

8.

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

3a + b = 21

5a + b = 35

Subtract the 2 equations:

=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0

=> The solution is  y = 7x

9.

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

5a + b = 17

10a + b = 22

Subtract the 2 equations:

=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12

=> The solution is  y = x + 12

Hope this helps!

5=1/2x - 3 please help me out
liq [111]

Answer:

x = 16

Step-by-step explanation:

5 = 1/2(x) - 3

Add 3 to both sides.

8 = 1/2(x)

Rewrite for clarity.

1/2(x) = 8

x/2 = 8

Multiply both sides by 2.

x = 16.

Proof:

5 = 1/2(x) - 3

Substitute variable.

5 = 1/2(16) - 3

Multiply 1/2 and 16.

5 = 8 - 3

Subtract 3 from 8.

5 = 5
